SPECIFICATION forming part. of Letters Patent No. 366,088, dated July 5,1887.

Application filed September 27, ISRG. Serial No. 214,609. (No model.)

,may be used on stoves or furnaces of almost any description.

The vobjects of this invention are, iirst, to adapt a sliding stoveldoorand its appurtenances to serve as a Ventilating-register withoutadditional parts; secondly, to adapt such a door to so operate withoutsupplemental openings in the stove; thirdly, to adapt such a door, sooperating, to be securelyV fastened in its Ventilating position;fourthly, to adapt it to be securely fastened in each ot' its threeposit-ions by a simple fastening device; tifthly, to adapt it to be sofastened by a gravitating bolt; and, sixthly, to adapt the door properto be made with a projecting face and hollow back without interferingwith its operation as a Ventilating-register, as aforesaid.

Two sheets of drawings accompany this speciiication as part thereof.

Figure l of these drawings represents a front view of a cylindricalstove provided with my improved stove-door. Fig. 2 represents a verticalsection on the line 2 2, Fig. l. Fig. 3 represents a horizontal sectionon the line 3 3', Fig. l. Fig. 4 represents a vertical section throughthe door proper on the line 4 4, Fig. 3. Fig. 5 represents a top View ofthe door proper. Fig. G represents, on a smaller scale, a series ofhorizontal sections through the door and stove-front, showing the doorproper in its several positions of rest. Fig. 7 represents a front viewof a stove provided with a Ventilating stove-door, illustrating amodification of the same invention. Fig. 8 represents a horizontalsection on the line 8 8, Fig. 7; and Fig. 9 represents a series ofhorizontal sections in the form of diagrams, showdoor.

Like letters of reference i ndicate cori espond ing parts in the severaltigures.

In applying my invention to a stove or furnace, A, I attach thereto apair of horizontal guide-rails, B C, which are made to support a doorproper, D, (to which the term .doori hereinafterrefers) said rails beinglocated immediately above and immediately below the doorway E, which maybe surrounded byy a thin door-frame, F, having a corresponding opening,as shown; 4but this as a distinct part is not considered essential.Itt'orms part of what may be termed the front7 of the stove, which mustsimply be adapted to a sliding To the front of the stove the rails B Gand door D are conformed, being in the examples segments of circularrings, and the eX- tended door or the front of thcstove isprovided atone ot' the vertical edges of the former with ventilati 11g-openingsV,which are consequently unmasked or masked by the movements of the dooritself, without supplemental parts. In the example represented by Figs.l to 6, inclusive, said ventilatingvopenings are formed in the door D,and communicate with said doorway-opening E itself when unmasked, asseen in the second diagram in Fig. 6l, so as to obviate formingsupplemental openings in the stove. In the modification illustrated byFigs. 7 to 9 the ventilatingopenings V are formed in the stove-front,and the lateral extension of the doorD is imperforate. In both examplesprovision is made for fastening the door D in a position of restintermediate between closed and open, to unmask the Ventilating-openingswithout otherwise opening the stove. The same fastening device, G,coacts with three detents, H I J, in the respective positions ot' restof the door indicated in Figs. 6 and 9, and said fastening device is, bypreference, a gravitating bolt provided with a lifting-knob, K, saiddetents being formed by lugs on the lower guide-rail, G. Said bolt G, asshown, is superposed on the-outer surface of the door and is guided byslots L, Fig.4, occupied by studs on the bolt,into which a pair ofscrews are driven, one of these Screws servingto attach the knob K. Saiddetents I-I I J are formed in the shape ICO of notches by lugs on theouter edge of said guide-rail C. Both guide-rails are attached to thestove,together with said doorway-frame F, by bolts M, and the door isconstructed with lugs N, Figs. 2 and 5, on its upper and lower edges tocoact with guide-grooves formed by the rails B and @,respectively; butthese and like details of mechanical construction form no part of mypresent invention. The door D, Figs. rl to 6,"is, moreover, constructdwith a recessed back, so that its face may project flush with the outeredges of the guide-rails, or as may be desired, without rendering itunduly heavy and to facilitate litting or conforming it ribs O P, whichcoact with the stove-front in the closed and ventilated positions-of thedoor to resist the entrance of air at the edges of the doorway. Said ribO is of especial importance in connection with Ventilating-openings `inthe recessed door itself to resist the entrance of air through the doorand doorway when the door is closed (See Fig. 6.) In the modification,Figs. 7 to 9, there is no need for this rib, but the door is providedwith a rib, P, similar to the one so marked inFigs. l to 6.

Having thus described my said improvement in stove-doors, lclaim as myinvention and desire to patent under this specification- 1. Thecombination, substantially as herein specified, of the front of a stoveor furnace and a horizontally-sliding door of greater lateral extentthanthe doorway-opening in said front, one of the parts being providedwith Ventilating-openings which are masked and unmasked by sliding thedoor itself.

2. The combination of the front of a Vstove or furnace and ahorizontally-sliding door of greater lateral extent than thedoorway-opening in said front, and provided with ventilating-openingswhich are unmasked by bringing them opposite said doorway-opening bysliding the door, substantially as herein speciiied.

8. The combination of the front ofa stove or furnace, ahorizontally-sliding door of greater lateral extent than thedoorway-opening in said front, and means for fastening said door in aposition intermediate between closed and open,

substantially as herein specified, ventilatingopenings in one of theparts being unmasked in said position of the door.

4. The combination, substantially as herein specified, of the front of astove or furnace, a horizontally-sliding Ventilating-door of greaterlateral extent than the doorway-opening in said front, and provided witha suitable fastening device, and a guide-rail attached to said front andprovided with detents which coactv of rest of Athe door, substantiallyas herein* specified.

6. In combination with the front of a stove or furnace provided with asuitable doorwayopening, a horizontally-sliding door of greater lateralextent than said doorway-opening, and having a recessed back dividedvertically by a partition-rib, and Ventilating-openings on one side ofsaid-rib, which are unmaskedy by bringing them opposite saiddoorway-opening by sliding the door, substantially as herein specilied.
